ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
If an applet contains a codebase containing a space, such as "codebase="Java%20Classes", instead of loading it throws a ClassNotFoundException

With Java 1.4.2, the applet would load and run.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
  To reproduce the bug:
1) Go to: http://goldbug.com/mrj/spaces/life.html
==> ClassNotFoundException in console; applet does not load

HTML source:

<applet code=Life.class codebase="Java%20Classes" height=400 width=400>
<param name="side" value=50>
<param name="gridsize" value=8>
<param name="paused" value=true>
<param name="initstate" value="25,25,25,24,26,24,25,26,24,25">
</applet>


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expect compatibility with Java 1.4.2.
ACTUAL -
The applet threw a ClassNotFoundException

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
Use your own ArcTest.java demo. Create a folder called "Java Classes" and put the .class files into that folder. Then modify the example1.html code to contain 'codebase="Java%20Classes".'

Note: you need to put the applet on a Web server. The applet works fine if you run it locally.
